Re: perl script for adding information to c file.

You are searching for strings in this (or similar) form:
```
":&temperature \n"
[download]
```
Such a string in not present in your data.
Also, you are reverting %data back and forth. That's probably not what you need.

I tried to clear your code and make it run:

#!/usr/bin/perl
use warnings;
use strict;

my $code = *DATA;

my %data = (24 => 'temperature',
            25 => 'pressure',
            26 => 'humidity',
           );

my %nums = ( 24 => ": information1\n",
             25 => ": information2 \n",
             26 => ": information3 \n",
           );

%data = reverse %data;
my $test_string = '(' . join("|", keys %data) . ')' ;

while (<$code>){
    if (/$test_string/) {
        chomp;
        $_ .= $nums{$data{$1}};
    }
    print;
}

__DATA__
/*!

#include "ccode.h"
/*********************************************************************

void main_10ms(void)
{
temperature ( i need to add infomation before  string that found)
if {.....
......
if{........
.....
}else
{......
}
}
humidity( i need to add infomation before  string that found)
if {.....
......
if{........

}else

}

Do you really need two hashes? Having just one with the information like temperature => 'information1' would be much easier.

Hi choroba, Its working but i have one problem with this script, it adding information how many times sting found in c file. But i need to add only once.for example if temperature string found three times in c file, so it adding same information three times. if string found add information at once is enoghf. no need to add same information so many times(how many times string presents).because in my file i have repeated strings so its aadding same information several times. how can i rectify this.
